• ffmpeg use amix and adelay to play ad over song

  28 juin 2020, par snowkiterdude

  I have two mp3 files, one long and one short(a song and an ad). I need the ad to play over the song starting 15 seconds into the song. I also need the volume of the song to fade out/in slightly before and after the ad. I have tried using amix with adelay but just can't get it right.

  



  here is something close but broken.

  



  ffmpeg -i song.mp3 -i ad.mp3 -filter_complex "amix=inputs=2:duration=first:dropout_transition=2;adelay=0|15000" output.mp3


  



  How can I get the ad to mix with the song properly ?

  


• Upload and Play Any Video in web browser using php CI

  14 août 2017, par Roni Modak

  I have tried to upload any video and convert the video file to mp4 at the time of upload using ffmpeg. The shell command I tried :

  $input = base_url().'video_upload/'.$file_name;
  
  $output = video_upload/video_'.$video_data['username'].'_'.$dtd.'_'.$random_number.'.mp4';
  
  $convt = shell_exec('ffmpeg -i '.$input.' '.$output);

  But i am unable to play those converted video in the web browser.

• discord.py bot dosen't play music

  29 août 2022, par bon ho

  I'm making music bot with discord.py. but bot doesn't play music. code is alright but music played 0.000000001 seconds and terminated.

  


  my code :

  


  @tree.command(name="play", description="play music")
async def playmusic(interaction:Interaction,url_title:str,playfirst:bool=False):
  await interaction.response.send_message("I'm looking for music!!")
  guild=str(interaction.guild.id)
  try:
    queue[guild]
  except KeyError:
    queue[guild]=[]
  if interaction.user.voice is None:
    await interaction.edit_original_response(content="you must join any voice channel")
  else:
    voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
    if voice_client == None:
      await interaction.user.voice.channel.connect()
      voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
    player = await YTDLSource.from_url(url_title, loop=None)
    if playfirst and len(queue[guild])>1:
      queue[guild].insert(1,player)
    else:
      queue[guild].append(player)
    if not voice_client.is_playing():
      voice_client.play(player,after=nextsong(interaction))
      await interaction.edit_original_response(content=f"{player.title} playing!!")
    else:
      await interaction.edit_original_response(content=f"{player.title} enqueued!")
    await asyncio.sleep(7)
    await interaction.delete_original_response()


  


  nextsong :

  


  def nextsong(interaction:Interaction):
  guild=str(interaction.guild.id)
  print(f"end : {guild}")
  voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
  if len(queue[guild])>0:
    queue[guild].pop(0)
  if not voice_client is None:
    voice_client.stop()
  if not len(queue[guild])==0:
    voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=interaction.guild)
    voice_client.play(queue[guild][0],after=nextsong(interaction))


  


  output :

  


  end : 1012635532829921291
[INFO    ] discord.player: ffmpeg process 12 successfully terminated with return code of -11.
